Abstract

PURPOSE:To enable to perform real time recording with a simple construction, by a method wherein recording in the first color of a thermal transfer film is conducted on a real time basis, and then recording in the second color and recording in the third color are conducted at high speed while sequentially returning a recording paper. CONSTITUTION:The first color Y part of the thermal transfer film 1 is matched to the position of a thermal head, recording is started in this condition, and the recording paper 2 is fed at a predetermined velocity. At this time, a CPU stores input signals S1... into an RAM through preamplifiers PA1... and A/D converters AD1..., and effects real time recording. When recording with the color Y part is completed by feeding the paper 2 by a predetermined length and the color Y part is replaced by a color M part, the paper 2 is rewound to the initial position, then it is fed at a high velocity together with the color M part to record overlappingly, and overlapping recording in a color C is similarly conducted. Thereafter, recording is conducted at high speed in a manner similar to that of recording in the second and third colors, and real time recording is immediately restarted. Accordingly, real time recording can be performed with a simple construction.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal transfer color recording apparatus that performs color recording using a thermal transfer method.

In general, thermal transfer recording devices transfer the ink onto the recording paper by placing a thermal transfer film coated with heat-melting ink on the surface of the recording paper and heating it using a heat-generating head. , it is designed to record. In addition, a thermal transfer color recording device that applies this principle uses a thermal transfer film that is dyed in the three primary colors of yellow, magenta, and cyan at regular intervals.
A recording device that expresses a plurality of tones by sequentially overlapping these colors has been put into practical use.

That is, each time the color of the thermal transfer film changes, the recording paper is returned to its original position and the same area is successively traced in different colors, thereby overlapping the colors at an arbitrary ratio to obtain a color record.

However, such thermal transfer color recording devices were mainly developed as devices for converting information displayed on display devices of personal computers into hard copies, and for example, outputting A4 ¥11 screens in batch format. Therefore, it is not suitable for real-time recording like general recording devices.

The present invention eliminates the above-mentioned drawbacks of conventional devices and provides a simplified thermal transfer color recording device capable of real-time recording. 1′
The purpose is to realize this with an i-like configuration.

The non-thermal color recording device of the present invention can be used with a conventional device as described above, or with an output of one screen (A 4 Jull).
), whereas the thermal transfer film has three primary colors of yellow, macenta, and cyan. At the same time, the recording operation is performed in real time in line with the recording using the first color of the thermal transfer film.
After the recording of the second color is completed, one recording using the second and third colors is performed at high speed while the recording paper is returned to its original position one by one.

Hereinafter, the thermal transfer V color recording apparatus of the present invention will be explained using the drawings.

FIG. 1 is a 110 diagram showing an embodiment of the thermal transfer color recording apparatus of the present invention. In the figure, 1 is a thermal roller 7 painted with three primary colors of ink: yellow, macenta, and cyan.
2 is a recording paper; 3 is a paper feed roller that feeds the recording paper 2 in an arbitrary direction; and 4 is a heat generating head that heats the heat transfer film 1 to perform transfer recording. The heat generating head 4 is a multi-stylus type heat generating head, and a large number of heat generating elements are arranged perpendicularly to the feeding direction of the recording paper 2. Thermal transfer film 1 is fed in synchronization with recording paper 2, and overlaps with recording paper 2 at the position of heating pad 4.

FIG. 2 is a view of the thermal transfer film 1 and the recording paper 2 viewed from the direction of their moving force. As shown in the figure, the thermal transfer film 1 is painted in series in the order of yellow (Y), magenta (M), and cyan (C) with a narrow width of, for example, about 10 mm.

The data are sequentially sampled via the memory device RAM and stored in the storage device RAM. That is, the recording operation is performed using the input signal Sl stored in the storage device RAM in accordance with the feeding speed of the recording paper.
S2... is read out sequentially, and the heating head (

111J The operation of the thermal transfer color recording apparatus of the present invention constructed as shown in FIGS. 1 to 3 is as follows. First, assuming that yellow (Y) is the first color, recording starts with the yellow (Y) portion of the thermal transfer film 1 aligned with the position of the heat generating head 4, and the recording paper 2 is is fed at the specified feed rate. At this time, the microprocessor CPLI sends 1 to the preamplifier P.

Input signal s1.I, AD2, . s
2... are stored in the storage device RAM, and real-time recording is performed using these input signals s1, s2.... That is, during this period, recording of the yellow component in each recording waveform is performed,
Regarding the recording waveform of the recording color including the yellow component, the signal state can be monitored in real time.

Next, the recording paper 2 is advanced 10 mm, and when the yellow (Y) part on the thermal transfer film 1 is completed and the color changes to magenta (M), which is the second color, the recording paper 2 returns to the original starting position. It is rewound and now the thermal transfer film 1
It will be sent together with the magenta commercial) part.

At this time, the input signal used for recording SI S2...
is also traced back to the start point, and the microprocessor CPU receives the input signal s traced back to the start point.
1, s2, etc. are read from the storage device RAM, and the same waveform as the recorded waveform written in the song is overwritten for the magenta component. Note that recording for this second color is performed using input signals s1, s1, and s1, which are already stored in the storage device RAM.
Since it is only necessary to read and output s2..., the feeding speed of the recording paper 2 can be made the highest, and recording can be completed in a short time. Also, the third color is cyan (
The records for C) are also similar, No. 2, No. 31'.
Recording in the color 1 is carried out in a short period of time.

In this way, one cycle of recording ends when the recording up to the third color is completed, and the recording waveform is expressed in the desired color.

Now, after one cycle of recording as shown in "-" is completed, the recording operation returns to the recording for the first color as shown in "l\+1", but at this time, the memory device RAM stores the previous color. The incoming J signals Sl, S2, .
. is already stored, the input signal for this period is recorded at the beginning of real-time recording. This part is recorded in the second and third records written in IIIJ.
As with the recording for the th color, only the contents of the storage RAM are output, so this is done at high speed and it is possible to immediately shift to real-time recording. Therefore, by repeating the recording operation as described above, it is possible to obtain almost real-time recording.

As explained above, in the thermal transfer color recording device of the present invention, a thermal transfer film in which the three primary colors of yellow, magenta, and cyan are coated in series with a narrow width of, for example, 10 mm is used. The recording operation is performed in real time for recording using the first color, and after the first color is completed, the recording paper is returned to its original position sequentially and the second and third colors are recorded. Since recording is performed at high speed using the following colors, a thermal transfer color recording device capable of real-time recording can be realized with a simple configuration.
